Event Notifications of Program Landscape Alterations

1. A computer-implemented method comprising: initiating a first enterprise solution instance in a first computer system, wherein a second enterprise solution instance is installed in a second computer system; monitoring, by the first enterprise solution instance, the first computer system for a change regarding an application within the first enterprise solution instance, the change comprising alteration or installation of the application; detecting, by the first enterprise solution instance, the change regarding the application; determining, by the first enterprise solution instance, aspects of the change; generating, by the first enterprise solution instance, an event notification including information corresponding to the determined aspects of the change; and sending the event notification including event information from the first enterprise solution instance to the second enterprise solution instance, wherein the second enterprise solution instance offers a user of the second computer system to make the detected change also with regard to the second computer system.

2. The method of claim 1 wherein monitoring the first computer system includes monitoring a registry of an operating system for the addition of a new entry.

3. The method of claim 1 wherein determining aspects of the change includes determining a name of the application.

4. The method of claim 3 wherein: generating the event notification including information corresponding to the determined aspects of the change includes generating the event notification as including the determined name of the application; and sending the event notification including the event information from the first computer system to the second computer system includes sending the event notification including the determined name of the application.

5. The method of claim 1 wherein determining aspects of the change includes determining a time of the change.

6. The method of claim 5 wherein: generating the event notification including information corresponding to the determined aspects of the change includes generating the event notification as including the determined time of the change; and sending the event notification including the event information from the first computer system to the second computer system includes sending the event notification including the determined time of the change.

7. The method of claim 1 wherein determining aspects of the change includes determining a type of activity related to the change.

8. The method of claim 7 wherein: generating the event notification including information corresponding to the determined aspects of the change includes generating the event notification as including the type of activity related to the change; and sending the event notification including the event information from the first computer system to the second computer system includes sending the event notification including the type of activity related to the change.

9. The method of claim 1 wherein determining aspects of the change includes determining a physical location related to the change.

10. The method of claim 9 wherein: generating the event notification including information corresponding to the determined aspects of the change includes generating the event notification as including the physical location related to the change; and sending the event notification including the event information from the first computer system to the second computer system includes sending the event notification including the physical location related to the change.

11. The method of claim 1 wherein determining aspects of the change includes determining an identity of an operator involved in the change.

12. The method of claim 11 wherein: generating the event notification including information corresponding to the determined aspects of the change includes generating the event notification as including the identity of the operator involved in the change; and sending the event notification including the event information from the first computer system to the second computer system includes sending the event notification including the identity of the operator involved in the change.

13. The method of claim 1 further comprising: accessing a catalog of additional computer systems that have instances corresponding to the first enterprise solution instance; determining that the second computer system of the accessed catalog of additional computer systems should receive the event notification; and accessing notification criteria, wherein determining the second computer system of the accessed catalog of additional computer systems should receive the event notification includes determining that the second computer system of the accessed catalog of additional computer systems meets criteria of the accessed notification criteria.

14. The method of claim 13 wherein determining that the second computer system of the accessed catalog of additional computer systems meets criteria of the accessed notification criteria includes determining that the change relates to type of business or activity of which the second computer system is also related.

15. The method of claim 1 wherein the computer-implemented method is performed entirely at the first computer system.

16. The method of claim 1 further comprising sending information corresponding to the determined aspects of the change from the first computer system to a server.

17. The method of claim 16 further comprising: accessing a catalog of additional computer systems that have instances corresponding to the first enterprise solution instance; and determining that the second computer system of the accessed catalog of additional computer systems should receive the event notification; wherein: the server performs the accessing of the catalog of additional computer systems which are associated with the first computer system; the server performs the determining that the second computer system of the accessed catalog of additional computer systems should receive an event notification; the server performs the generating of the event notification including information corresponding to the determined aspects of the change; and the server performs the sending of the event notification including the event information from the first computer system to the second computer system.

18. The method of claim 17 further comprising, determining, at the server, additional information to be included in the event notification, wherein: generating the event notification includes generating the event notification as including: information corresponding to the determined aspects of the change received from the first computer system, and the additional information determined at the server; and sending the event notification to the second computer system includes sending the event notification including information corresponding to the determined aspects of the change and the additional information to the second computer system.

19. A computer program product tangibly embodied in a computer-readable storage medium and comprising instructions that when executed by a processor perform a method comprising: initiating a first enterprise solution instance in a first computer system, wherein a second enterprise solution instance is installed in a second computer system; monitoring, by the first enterprise solution instance, the first computer system for a change regarding an application within the first enterprise solution instance, the change comprising alteration or installation of the application; detecting, by the first enterprise solution instance, the change regarding the application; determining, by the first enterprise solution instance, aspects of the change; generating, by the first enterprise solution instance, an event notification including information corresponding to the determined aspects of the change; and sending the event notification including event information from the first enterprise solution instance to the second enterprise solution instance, wherein the second enterprise solution instance offers a user of the second computer system to make the detected change also with regard to the second computer system.
